Understanding the Fuel Additive Options

The reason that fuel additives can cause a great deal of confusion is that there are a wide range of different properties that the additive focusing on. The ideal way to use an additive is to address the specific problem that you have been having with your vehicle.

Here are some of the most common and why you should purchase products that provide each specific treatment:

• Fuel System Cleaner. As one of the highest quality of fuel additives, fuel system cleaners provides a full cleanse of all buildups. This should be added for the most severe problems and at the same time as an oil change.

• Gas Treatment. This additive focuses on the overall quality of the fuel. It does this by removing any deposits or water. The result of this is an increased fuel economy and most of the time this type of additive also provides anti-freezing qualities. A gas treatment is usually one of the lowest in prices and you should add this before filling up your tank.

• Fuel Stabilizer. Fuel is constantly breaking down from the moment it is pumped and as such it is important to stabilize it, especially if you are aiming to store the fuel for a long time. Use this additive to protect your tank and system from corrosive elements.

• Fuel Injection Cleaner. Use this additive to remove any clogs in the engine’s fuel injector. This should be used in the fuel tank when you are changing the oil.

1. PRI Fuel Stabilizer

The PRI Fuel Stabilizer is the best fuel additive because it works when you need it to and how you need it to, at all times. This is also a bottle that comes in the perfect size to use for one vehicle, though getting more would be recommended if you are maintaining and protecting the cars of your entire family.

You will notice that the acceleration you get using the gas with this additive is better and smoother overall. This makes this product a great buy to enhance overall performance.

2. STA-BIL Fuel Stabilizer

When you leave gas in a lawn mower or any kind of older vehicle, using the STA-BIL 22214 can take that fuel from being less than desirable to being usable. It can even improve the overall performance of the machine that it is powering.

It is recommended to add a small amount at a time to the fuel until you reach the right ratio. This is a stabilizer that obviously works better with fresh gas but it can help you get more life out of gas that hasn’t been used in a long time.

Using this product will make things better for your vehicles and machines and will also provide much better performance. Even this small bottle will get you through a lot of fuel when you add just a little at a time.
